[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0025] First embodiment:

[0026] See also Figure 1 to Figure 5 ,in Figure 1 This is a front view of the first embodiment of the utility model. Figure 2 The utility model Figure 1 The cross-sectional view along the AA line. Figure 3 The utility model Figure 2 A partial enlarged view of point B in the middle.

[0027] The utility model provides an asphalt paving device for road construction, comprising a shovel head 101, a long bolt 102, a fixing bolt 103 and a gripping rod 104. The above-mentioned scheme solves the technical problem that the gripping rod 104 and the shovel head 101 in the above-mentioned structure are connected by direct plugging, which is a relatively simple connection method and requires a large external force when disassembling and assembling the gripping rod 104.

[0028] According to this specific embodiment, two support blocks 105 are provided on the top of the shovel head 101, and a socket 106 is provided on the top of the shovel head 101. A nut 107 is provided at one end of the long bolt 102, and a block 108 is provided at one end of the grip rod 104. A plug rod 109 is provided in the grip rod 104 for sliding. The two support blocks 105 are respectively supported by the long bolt 102 and the block 108, and are located on both sides of the block 108. The long bolt 102 passes through the square. Block 108, the insertion rod 109 is plugged into the shovel head 101 and is located in the insertion hole 106, the fixing bolt 103 is threadedly connected to the insertion rod 109, is located on the outside of the insertion rod 109, and passes through the block 108, and the shovel head 101 and the gripping rod 104 are connected by the two supporting blocks 105 and the long bolt 102, so as to prevent the shovel head 101 from being completely separated from the gripping rod 104, and the quick disassembly and assembly can be achieved under the action of the insertion rod 109.

[0029] The handle 104 and the block 108 both have a through hole 110 . Since the handle 104 and the block 108 are both made of aluminum alloy, the provision of the through hole 110 can reduce the use of materials and reduce the overall weight of the handle 104 .

[0030] Secondly, a T-shaped block 111 is provided at one end of the insertion rod 109, and a slide groove 112 is provided at one end of the gripping rod 104. The T-shaped block 111 is slidably connected to the gripping rod 104 and is located in the slide groove 112. The insertion rod 109 can be easily moved through the T-shaped block 111, so that the insertion rod 109 can be removed from or inserted into the slot.

[0031] When the utility model is used to connect the shovel head 101 and the grip rod 104, the shovel head 101 is docked with the grip rod 104, so that the two support blocks 105 are located on both sides of the block 108, and then the long bolt 102 is passed through the two support blocks 105 and the block 108, and the nut 107 is used to fix them. It should be noted that the nut 107 does not directly contact the support block 105. This design allows the shovel head 101 to rotate outside the block 108, thereby The insertion hole 106 is aligned with the insertion rod 109, and then the insertion rod 109 is slid to insert the insertion rod 109 into the insertion hole 106. Finally, the insertion rod 109 is fastened by the fixing bolt 103 to prevent the insertion rod 109 from loosening. In this way, the technical problem that the handle 104 and the shovel head 101 in the above structure are connected by direct plug-in, which is relatively simple and requires a large external force when disassembling and assembling the handle 104 is solved.

[0032] The second embodiment is:

[0033] Based on the first embodiment, please refer to Figure 6 to Figure 9 ,in Figure 6 It is a three-dimensional stereogram of the second embodiment of the utility model. Figure 7 It is a front view of the second embodiment of the utility model. Figure 8 The utility model Figure 7 The cross-sectional view of the EE line, Fig. 9 The utility model Figure 8 A partial enlarged view of point F in the middle.

[0034] The utility model provides an asphalt paving device for road construction, which also includes two protection mechanisms and a handle 201 . The protection mechanism includes an anti-slip cover 203 and a protection cover 204 .

[0035] According to this specific embodiment, the two protective mechanisms are respectively arranged at the middle part and the other end of the grip rod 104, and the handle 201 is threadedly connected to the grip rod 104 and is sleeved on the end of the grip rod 104. The handle 201 can be used to easily lift or hang the grip rod 104, and the setting of the handle 201 can save effort.

[0036] The handle 201 is covered with a silicone sleeve 202 , which can effectively prevent damage from ultraviolet rays and provide a good anti-slip effect.

[0037] Secondly, the protective sleeve 204 is composed of an internal thread end 205, a supporting end 206 and a protective end 207. Two external thread rings 208 are arranged on the outer side of the grip rod 104. The anti-slip sleeve 203 is bonded to the grip rod 104 and sleeved on the outer side of the grip rod 104. The supporting end 206 is slidably connected to the grip rod 104 and sleeved on the outer side of the grip rod 104. The protective end 207 is slidably connected to the anti-slip sleeve 203 and covered on the outer side of the anti-slip sleeve 203. The internal thread end 205 is adapted to the external thread ring 208. By holding the protective cover 204, the protective cover 204 is moved out from the anti-slip cover 203, and the internal thread end 205 is connected to the external thread ring 208, so that the grip 104 can be easily used under the action of the anti-slip cover 203. When it is not used for a long time, the protective cover 204 is rotated to make the internal thread end 205 detach from the external thread ring 208, and then the protective cover 204 is slid to make the protective end 207 be sleeved on the anti-slip cover 203, so as to prevent the anti-slip cover 203 from being exposed to the sun for a long time.

[0038] By using the asphalt paving device for road construction of the present embodiment, the handle 201 can be used to conveniently lift or hang the grip rod 104, and the setting of the handle 201 can conveniently play a labor-saving role. The setting of the silicone sleeve 202 can effectively prevent the damage of ultraviolet rays and provide a good anti-slip effect. The protective sleeve 204 is held to be moved out of the anti-slip sleeve 203, and the internal thread end 205 is connected to the external thread ring 208, so that the grip rod 104 can be conveniently used under the action of the anti-slip sleeve 203. When it is not used for a long time, the internal thread end 205 can be separated from the external thread ring 208 by rotating the protective sleeve 204, and then the protective sleeve 204 is slid so that the protective end 207 is sleeved on the anti-slip sleeve 203, thereby preventing the anti-slip sleeve 203 from being exposed to the sun for a long time.

[0039] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope covered by the utility model.
